The reported free/reduced lunch eligible measure is from 2024–25: Garcia’s share was 77%, Morris’s 82%, Birney’s 91% and Lincoln’s 91%; these figures describe school context, not the cause of test results. Because schools serve different grade spans, grade-specific comparisons can be more useful than school-wide figures.
